lTO WHOM IT AMAY GONCERN: A l

Beit known that I, JOHN Wasrovun, of Taylor Post-Oiiice, vin the countyfof Ogle, vand State of Illinois, t have invented anew and usefulImprovementin lLlevators;` and do declare that the following 'is a trueand i accurate description' thereof, reference being had to theaccompanying drawings, and to-the letters of reference marked thereon,and being a part o'f this specification, in'which like lettersindicatelike parts in each ligure.

'Figure 1 is a top view.

Figure 2 isa side elevation,

Figure 3 is 4'a front view'of the extension-arm.

Figure 4 is a bottom view of the same.

The nature of my invention consists in constructing an elevator, for thepurposeof raising a wagon-box or hay-rack filled with grain, hay, straw,or other heavy material, in the field, for building stacks equally aswell' asn theharn, for the purpose of raising hay to the level ofthebays', and is'easily moved from place to,plaee, being provided withadjustable wheels for that purpose. l y

To construct my apparatus, I build a frame, A, surmounted by theplatform B, upon which I erect the standards C, at the top of which Iplace the sheaves D. i Y

'E are wside-timbers, secured to the standards C, in the front ofwhiclris journalled the shaft F, at the'centre of which is secured theratchet-drum G, held-in position by the pawl H, and Vsecured by the stopI. i. Y

J are wheels, revolving upon proper axles ,in the pedestalsiK pivoted tothe-,rear ends ofthe side-timbers E'. These pedestals are secured in anupright position by means of-the pinsI L wheni'tis desired .tomove the.apparatus.

M are horizontal rods, provided with guides, N,'sliding in grooves inthe standards C.. l

O are guide-pulleys at the sides of the two rear standards. I. Y A, 4

P are elevating-ropes, secured lto the horizontal rods M, and runningover the sheaves D, the two rearA ones also under the guide-pulleys '0,and wound upon the Ashaft F by unwinding the drag-rope Q'from the ldrumG, and to which the team is attached by means of a'proper hook orotherdevice. l R are transverse extensionearms, which are intended to form.the base of a hay-rack, or may be secured to a, wagon-box by properhooks, and are so constructed that by means ofthecrossed cordsrunning'over suitable pulleys, and secured alternately to the inner endsofthe extensionsarins R1 and Rz, when eitherof them Vis drawn out orretired, the corresponding one is caused togadvanceor retire at the sametime.

To operate myapparatus, we will suppose it to be placed yalongside of ahay-stack in course of erection.

"The wagon, represented in the drawings by the block of woods, issurmounted by a hay-rack, resting upon the extension-arms It, isdrawn-upon the platform VB, the horsesstraddling the drum G as they passo, stopping immediately after passing off, which will bringthedouble-tree's .directly overthe drum. The double-trees are thendetached from Athe tongue of the wagon, and attached 'to the hook on-thedrag-rope l The sliding arms R1 and R2 are then drawn out so as toproject over therhorizontal bars M The team is then driven' ahead. Asthe mg-rope unwinds from the drum G, the elevating-ropes P are woundupon the shaft F, and the rack, with its load, is elevated to thedesired height, the Apawl H retainingthe drum G in its position, and, ifnecessary, the stop I may be used to insure greater safety. Y 4

After the hay is unloaded from the rack to the topof the stack, hythrowing the pawl H out of gear, the rack willl he lowered on tothewagon, by its own weight, asithe team is backed up; the drag-rope Qbeing re-wound upon the drum G, ready for elevating the next load. y l IThis apparatus serves equally as well for elevating hay or straw-in thebarn, being placed on thejloor between the bays. To move lit from placeto place, the rear end is slightly elevated, bringing the pedestals K toa vertical position, where they are secured by the pins L. The front endof the'machinemay be'seeured t0 the rear axle of a wagon, or rest upon.the rear end of the box, when the whole may be moved with ease. V

What I claim as my invention, andpdesire to secure by Letters Patent, isi 1. The extension-arms.RI and R2, in connection with any suitablehay-rack or wagon-box, when used for the purposes herein described andset forth. l

2. The combination and arrangement of the frame A, platform B, standardsC, provided with sheaves D and guide-pulleys O, the side-timbers E,pedestal K, wheels J and pins L, the shaft F, drum G, pawl H, stop I,horizontal bars M, guides N, elevator-ropes P, and drag-ropes Q, inconnection with the extension-arms Rl and R2, when constructed,arranged, and-operating substantially as described, and for the purposesherein set forth.
